3 Routine care, SATA drive guidelines, and disassembly preparation This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service. CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system board. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
Preventing electrostatic damage to equipment Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of sensitivity. The following packaging and grounding precautions are necessary to prevent damage to electric components and accessories. ● To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes. ● Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.
Recommended materials and equipment Materials and equipment that are recommended for use in preventing static electricity include: ● Antistatic tape ● Antistatic smocks, aprons, or sleeve protectors ● Conductive bins and other assembly or soldering aids ● Conductive foam ● Conductive tabletop workstations with ground cord of one-megohm +/- 10% resistance ● Static-dissipative table or floor mats with hard tie to ground ● Field service kits ● Static awareness labels ● Wrist straps and footwea
● Never cover the ventilation slots on the monitor with any type of material. ● Install or enable power management functions of the operating system or other software, including sleep states. Routine care General cleaning safety precautions 1. Never use solvents or flammable solutions to clean the computer. 2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth on the component. 3.
● If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets. CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard may not function properly. ● Cleaning under a key may be done with a swab moistened with isopropyl alcohol and squeezed out. Be careful not to wipe away lubricants necessary for proper key functions.
CAUTION: Metric screws have a black finish. U.S. screws have a silver finish and are used on hard drives only. CAUTION: As each subassembly is removed from the computer, it should be placed away from the work area to prevent damage. Cables and connectors Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the connector.
SATA hard drives Serial ATA Hard Drive Characteristics Number of pins/conductors in data cable 7/7 Number of pins in power cable 15 Maximum data cable length 39.37 in (100 cm) Data interface voltage differential 400-700 mV Drive voltages 3.3 V, 5 V, 12 V Jumpers for configuring drive N/A Data transfer rate 6.0 Gb/s SATA hard drive cables SATA data cable Always use an HP approved SATA 6.0 Gb/s cable as it is fully backwards compatible with the SATA 1.5 Gb/s drives.
Cable management Always follow good cable management practices when working inside the computer. 16 ● Keep cables away from major heat sources like the heat sink. ● Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these are not designed to take excessive pressure on them. ● Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when the parts are moved. ● When folding a flat ribbon cable, never fold to a sharp crease.
